Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying systems and relates to a roller with rubber coating that can be quickly replaced. Background Art

[0002] The rubber coating of the roller is an important part and component of the belt conveyor. The rubber coated roller can increase the friction between the belt and the roller surface, effectively improve the operation of the conveying system, prevent the slip between the roller and the belt, reduce the belt slippage, and make the roller and the belt run synchronously.

[0003] There are two main ways of rubber lagging for rollers in the prior art: one is to use the "hot sulfur type" technology, that is, the rubber lagging is vulcanized on the roller. When the rubber lagging is replaced, the roller must be removed from the conveyor and then pulled to the factory for processing. The labor intensity of the workers is high, the cost consumption is high, and the replacement efficiency is low; the other is to use the "cold sulfur type" technology, and the rubber lagging is pasted on the metal roller with adhesive. Although the metal roller does not need to be disassembled during replacement, the surface of the metal roller needs to be cleaned. The process is complicated and time-consuming. At the same time, the poor environment at the working site will also affect the quality of the rubber lagging, and the replacement efficiency is also low. Utility Model Content

[0004] The utility model aims to provide a roller with a rubber coating that can be quickly replaced, thereby solving the problems in the prior art of high labor intensity, long time consumption, high cost consumption and low replacement efficiency.

[0005] The technical solution adopted by the utility model is that the rubber-coated roller can be quickly replaced, comprising a roller body, fixed covers are matchedly arranged on both ends of the roller body, and the fixed covers are connected to the roller body through second bolts; rubber-coated components are symmetrically arranged on the outer walls of both ends of the roller body.

[0006] The utility model is also characterized in that:

[0007] The rubber-coated assembly comprises a positioning block, which is embedded in the outer wall end side of the drum body along the axial direction of the drum body; first bolts are respectively arranged on both sides of the positioning block, and the first bolts are fixed to the drum body through nuts.

[0008] Each rubber lagging assembly includes at least four first bolts.

[0009] The nut is welded to the inner wall of the drum body.

[0010] At least 8 rubber-coated components are provided.

[0011] The rubber-coated components are arranged with equal arc length on the outer walls at both ends of the drum body.

[0012] The beneficial effects of the utility model are:

[0013] The utility model can quickly replace the rubber-coated roller. After it is put into use, the equipment maintenance personnel can replace the rubber coating on site. It only takes about three hours to complete the rubber coating work of a roller, which greatly reduces the output of manpower and material resources and continuously saves costs for the company.

[0019] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0020] The utility model can quickly replace the rubber-coated roller, such as Figure 1 As shown, it includes a drum body 1, and fixed covers 2 are provided on both ends of the drum body 1. The fixed covers 2 are connected to the drum body 1 through second bolts 4; the fixed covers 2 are as shown in FIG. Figure 2 As shown, the overall rigidity of the roller is increased to prevent its axial movement; rubber-coated components 3 are symmetrically arranged on the outer walls of both ends of the roller body 1. At least 8 rubber-coated components 3 are arranged, and are installed on the outer walls of both ends of the roller body 1 with equal arc lengths, as shown in FIG. Figure 3 shown.

[0021] like Figure 4 As shown, the rubber-coated assembly 3 includes a positioning block 32, which is embedded in the outer wall end side of the drum body 1 along the axial direction of the drum body 1; first bolts 31 are respectively arranged on both sides of the positioning block 32, and each rubber-coated assembly includes at least 4 first bolts 31; the first bolts 31 are fixed to the drum body 1 through nuts 33; the nuts 33 are welded to the inner wall of the drum body 1 to prevent the nuts from loosening or losing, thereby reducing the maintenance process. The positioning block 32 can be quickly positioned, and at the same time, cooperate with the first bolts 31 and the nuts 33 to prevent the outer rubber from moving.

[0022] The setting of the rubber-coated component 3 makes it possible to replace the outer rubber coating on the machine compared with the traditional rubber-coated roller without completely disassembling the roller, which greatly simplifies the maintenance efficiency.

[0023] The working principle of this utility model:

[0024] At least 8 rubber lagging components 3 are fixed symmetrically and with equal arc lengths on the drum body 1 in sequence, and then the fixing cover 2 is fixed to the two ends of the drum body 1 with a plurality of second bolts 4. When replacing the rubber lagging, the first bolt 31 is removed, and the film is laid on the drum body 1 according to the position of the positioning block 32. The four corners of the film are fixed by the first bolts 31, and the replacement of the rubber lagging can be completed quickly and conveniently on the machine.
